Plankalkül programming language(plankalkül ) Developer Hiring Guide

Plankalkül is recognized as the first high-level, non-von Neumann programming language, conceived by German engineer Konrad Zuse between 1943-1945. It was designed during World War II for engineering purposes but remained theoretical and unpublished until 1972 due to wartime circumstances. The language featured data structures and a binary floating-point number system, embodying concepts prevalent in modern programming languages. However, it was not implemented in Zuse's time; the first implementation occurred in 1998 at Berlin's Free University. Its historical significance lies in its pioneering status as a precursor to contemporary algorithmic languages (source: "The Computer - an Illustrated History" by Mark Frauenfelder).

First 20 minutes

General Plankalkül programming language(plankalkül ) app knowledge and experience

The first 20 minutes of the interview should seek to understand the candidate's general background in Plankalkül programming language(plankalkül ) application development, including their experience with various programming languages, databases, and their approach to designing scalable and maintainable systems.

How would you define Plankalkül?
Plankalkül is the first high-level programming language in the world designed by Konrad Zuse between 1942 and 1945. It was ahead of its time, being developed before the first electronic computers were built.
What are the key features of Plankalkül?
Plankalkül is a procedural language that supports arrays, records, conditional and loop statements. It also supports floating point arithmetic and has a notation for algebraic equations.
Describe the difference between Plankalkül and modern programming languages.
While Plankalkül laid the foundation for many concepts used in modern programming languages, it differs in several ways. For instance, it was not designed with the idea of a stored program computer in mind, and it lacks many features of modern languages such as object-oriented programming.
How would you write a simple program in Plankalkül?
A simple program in Plankalkül might look like this: P1 max(X[1:100] ? R1) := X[1] ? R1; FOR K2 := 2, 1, 100 DO X[K2] > R1 ? IF R1 THEN X[K2] ? R1 END; END. This program finds the maximum value in an array.
What are the data types supported by Plankalkül?
Plankalkül supports several data types, including floating point numbers, boolean values, and arrays.

Next 20 minutes

Specific Plankalkül programming language(plankalkül ) development questions

The next 20 minutes of the interview should focus on the candidate's expertise with specific backend frameworks, their understanding of RESTful APIs, and their experience in handling data storage and retrieval efficiently.

How would you implement a loop in Plankalkül?
Loops in Plankalkül can be implemented using the FOR statement. For example, FOR K2 := 2, 1, 100 DO X[K2] > R1 ? IF R1 THEN X[K2] ? R1 END; END. This loop iterates over an array from the second to the hundredth element.
Describe the difference between the IF statement in Plankalkül and in modern programming languages.
In Plankalkül, the IF statement is used as part of an expression, not as a standalone control structure. The condition is followed by a '?' symbol and then the expression to be evaluated if the condition is true.
How would you handle errors in Plankalkül?
Plankalkül does not have built-in error handling mechanisms like try-catch blocks in modern languages. Errors would have to be handled manually by checking conditions and adjusting program flow accordingly.
What are the limitations of Plankalkül?
Plankalkül lacks many features of modern programming languages, such as object-oriented programming, functions or procedures, and built-in error handling. It also does not have a standard library or any form of I/O operations.
How would you optimize a Plankalkül program?
Optimizing a Plankalkül program would involve manual techniques such as minimizing the number of operations, optimizing loop structures, and reducing the use of memory.

The ideal back-end app developer

What you’re looking to see on the Plankalkül programming language(plankalkül ) engineer at this point.

At this point, a skilled Plankalkül programming language(plankalkül ) engineer should demonstrate strong problem-solving abilities, proficiency in Plankalkül programming language(plankalkül ) programming language, and knowledge of software development methodologies. Red flags include lack of hands-on experience, inability to articulate complex concepts, or unfamiliarity with standard coding practices.

Digging deeper

Code questions

These will help you see the candidate's real-world development capabilities with Plankalkül programming language(plankalkül ).

What does this basic Plankalkül code do?
P1(0) := 0
This code assigns the value 0 to the variable P1(0). It's a simple assignment operation.
What does this Plankalkül code do?
P1(0) := 0; P1(1) := 1; P1(2) := P1(0) + P1(1)
This code assigns the value 0 to the variable P1(0), assigns the value 1 to the variable P1(1), and then assigns the sum of P1(0) and P1(1) to the variable P1(2).
What does this Plankalkül code do?
P1(0) := 0; P1(1) := 1; for i := 2 to 10 do P1(i) := P1(i-1) + P1(i-2)
This code initializes the first two elements of an array P1 with values 0 and 1. Then it fills the rest of the array with the sum of the previous two elements. This is essentially generating the Fibonacci sequence.
What does this Plankalkül code do?
P1(0) := 0; P1(1) := 1; for i := 2 to 10 parallel do P1(i) := P1(i-1) + P1(i-2)
This code does the same thing as the previous code, but it uses parallel processing to calculate the Fibonacci sequence. The 'parallel do' keyword allows for concurrent execution of the loop iterations.

Wrap-up questions

Final candidate for Plankalkül programming language(plankalkül ) Developer role questions

The final few questions should evaluate the candidate's teamwork, communication, and problem-solving skills. Additionally, assess their knowledge of microservices architecture, serverless computing, and how they handle Plankalkül programming language(plankalkül ) application deployments. Inquire about their experience in handling system failures and their approach to debugging and troubleshooting.

Describe the difference between Plankalkül and assembly language.
Plankalkül is a high-level language with a syntax designed to be readable by humans, while assembly language is a low-level language that closely corresponds to machine code. Plankalkül programs need to be translated into machine code before they can be run, while assembly language programs can be run directly by the computer.
How would you translate a Plankalkül program into machine code?
Translating a Plankalkül program into machine code would require a compiler. However, no such compiler exists, as Plankalkül was never implemented during its time.
What are the challenges in implementing Plankalkül on modern computers?
Implementing Plankalkül on modern computers would be challenging due to its lack of many features that are standard in modern programming languages, such as I/O operations, error handling, and a standard library. Additionally, its syntax and semantics are quite different from those of modern languages.
